我正在尝试将Camel与Spring 5集成（使用注释 - 没有XML！）并且在我的JUnit测试中遇到了一些问题。我能够在JUnit运行时启动Camel，但是我试图在测试过程中调用的Spring控制器对象没有得到自动装配。
我的Junit在下面;
public class ListCaseNotesTest extends CamelSpringTestSupport {
@Override
protected AbstractApplicationContext createApplicationContext() {
AnnotationConfigApplicationContext acc = new AnnotationConfigApplicationContext();
acc.register(CamelController.class);
return acc;
}
@Autowired
VisitsController visitsController;
@Test
public void testListCaseNotes() throws Exception{
ListNotesKey listNotesKey = new ListNotesKey();
listNotesKey.setUsername("caseworker");
listNotesKey.setRelatedIDs("[\"1000\",\"1001\",\"1002\"]");
listNotesKey.setRelatedType(ListNotesKey.RelatedTypeEnum.CASE);
// invoke camel
String response = visitsController.sendMessage("listCaseNotes", SOR_CONFIG, payload);
为简洁起见，我省略了响应验证 - 当调用sendMessage时，我收到的异常是NullPointerException。完整的日志如下;

我需要做什么来设置我的JUnit测试，以便Spring bean成功自动装配？
提前致谢！

根据https://camel.apache.org/spring-testing.html，CamelSpringTestSupport不处理Spring注释。如果你坚持扩展它，你可以从applicationContext字段获取你的上下文并手动获得正确的bean：
applicationContext.getBean(VisitsController.class).sendMessage("listCaseNotes", SOR_CONFIG, payload)
或者切换到Cammel runner @RunWith(org.apache.camel.test.junit4.CamelSpringJUnit4ClassRunner)。
